The Defender is a micro-size 1911 with a 3-inch bushingless bull barrel and a dual nested recoil spring system with a reverse plug, designed to manage .45 ACP in a compact format. It uses a single-action, locked-breech operation consistent with Colt’s Series 90 architecture and incorporates a firing pin block safety.
The lightweight aluminum alloy frame wears a Stainless Cerakote finish and a smooth, uncheckered front strap for a clean carry profile. Up top, the stainless slide shows polished flats, angled rear cocking serrations, and a lowered and flared ejection port. The two-tone presentation pairs the stainless slide with the Stainless Cerakote-finished alloy frame.
Sighting is handled by dovetailed Novak LoMount 3-dot sights: a white-dot front blade and a windage-adjustable rear secured by a set screw. Controls include a manual thumb safety and a beavertail grip safety with a memory pad. A skeletonized commander-style hammer and a medium-length, 3-hole skeletonized trigger round out the carry-focused setup.
Red/black checkered composite grips with molded Colt logos provide a secure purchase. Capacity is 7+1 with the included steel single-stack magazines. The factory case label confirms .45 ACP chambering, a 3-inch barrel, and model O7000XE.
